This is true in mid and late career, but not early. Lots of mathematically and engineering minded college students consider both CS and mech/aerospace as majors. Of course career prospects are a major influence. Also fwiw my wife left a 10 year aerospace career, moving from NASA to Google, largely for comp reasons. She was a structural aerospace engineer, now she’s a data scientist.
